Chris Lattner 90c4947df7 enhance basicaa to return "Mod" for a memcpy call when the 
queried location doesn't overlap the source, and add a testcase.

 2010-11-30 00:43:16 +00:00
Bill Wendling 62718de2b9 Add correct encoding for "bl __aeabi_read_tp". However, the asm matcher isn't 
able to match this yet.

Chris Lattner 9a146372b5 Teach basicaa that memset's modref set is at worst "mod" and never 
contains "ref".

Enhance DSE to use a modref query instead of a store-specific hack
to generalize the "ignore may-alias stores" optimization to handle
memset and memcpy.

Sean Callanan 348b5897f9 Added a feature where registers can be referred to 
using special $-variables from expressions.

(lldb) expr $rip

These variables are available for reading and
writing.

Jim Grosbach 027bd47e3e Rename BX/BRIND/etc patterns to clarify which is actually the BX instruction 
and which are pseudos.

Bill Wendling 85a8a72d85 Add some encoding for the adr instruction. Labels still need to be finished.

Owen Anderson e22c7322b8 Correct Thumb2 encodings for a much wider range of loads and stores.

Chris Lattner c3c754f750 my previous patch would cause us to start deleting some volatile 
stores, fix and add a testcase.

Chris Lattner d4f1090948 two changes to DSE that shouldn't affect anything: 
1. Don't bother trying to optimize:

lifetime.end(ptr)
store(ptr)

as it is undefined, and therefore shouldn't exist.

2. Move the 'storing a loaded pointer' xform up, simplifying
  the may-aliased store code.

Bob Wilson 318ce7cb3f Fix the encoding of VLD4-dup alignment. 
The only reasonable way I could find to do this is to provide an alternate
version of the addrmode6 operand with a different encoding function.  Use it
for all the VLD-dup instructions for the sake of consistency.

llvm-svn: 120358
 2010-11-30 00:00:42 +00:00
Bob Wilson 0b27b68164 Rename VLDnDUP instructions with double-spaced registers 
in an attempt to make things a little more consistent.

llvm-svn: 120357
 2010-11-30 00:00:38 +00:00
Bob Wilson 431ac4ef50 Add support for NEON VLD3-dup instructions. 
The encoding for alignment in VLD4-dup instructions is still a work in progress.

Johnny Chen c9ea0f8425 Add an expect() statement within breakpoint_conditions() method which tests that 
the process status is indeed 'stopped' before invoking 'frame variable -t val'
command to inspect the frame variable.  When I run the test suite, it sometimes
emits an output like:

runCmd: frame variable -t val
runCmd failed!
error: you must be stopped in a valid stack frame to view frame variables.

The expect() statement inserted is to make sure that the process is stopped and
we have a valid frame.
